1. The price elasticity of demand for chicken is estimated to be – 0.65. If the price of chicken increased by 6 percent, what will be the expected percentage decrease in the quantity of chicken sold?

2. The average price for personal computers has recently decreased from Rs.300 to Rs.250. As a result, the quantity of personal computers bought has increased by 20 percent. What would be the price elasticity of demand for personal computers?

3. The demand for Penn's Oil motor oil can be characterized by the following point elasticities: price elasticity = -2.5, cross-price elasticity with Value Lean motor oil = 1.5, and income elasticity = 0.75. Indicate whether each of the following statements is true or false, and explain your answer.

a. A price increase for Penn's Oil will decrease both the number of units demanded and the total revenue of sellers.

b. The cross-price elasticity indicates that a 2% increase in the price of Value Lean will cause a 3% increase in Penn's Oil demand.

c. Demand for Penn's Oil is price elastic and the motor oil is a cyclical, normal good.
